Core Mechanism of Action

As a chelating agent, EDTA-2Na works by forming stable, soluble complexes with polyvalent metal ions such as Fe2+, Fe3+, Ca2+, and Mg2+. In hard water environments, these metal ions can react with surfactants in cleaning formulations, reducing their effectiveness and causing issues like scum formation. By sequestering these ions, EDTA-2Na prevents such reactions, maintaining the performance of surfactants even in hard water and ensuring consistent cleaning efficiency. Additionally, metal ions can act as catalysts for oxidation and rancidity in personal care products, leading to degradation of active ingredients, color fading, and fragrance loss. EDTA-2Na’s ability to bind these ions inhibits these unwanted chemical reactions, preserving the integrity of product components and extending the overall shelf life of formulations.
